Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides glucose for cellular energy metabolism; sodium chloride and potassium chloride restore electrolyte balance and maintain osmotic gradients. Potassium is essential for neuronal conduction, muscle contraction, and acid-base regulation.
Magnesium sulfate provides magnesium ions, which are essential for various physiological processes. It acts as a cofactor for enzymatic reactions, stabilizes excitable membranes, and antagonizes calcium entry at the neuromuscular junction, leading to reduced acetylcholine release and muscle relaxation. In the CNS, it may act as a noncompetitive antagonist of NMDA receptors, exerting anticonvulsant effects.
Intravenous infusion; rate determined by fluid and electrolyte requirements. Typical adult dose: 1000-2000 mL over 24 hours, providing 5 g dextrose, 0.2 g sodium chloride, and 5 mEq potassium chloride per 100 mL. Infusion rate not to exceed 25 mL/hr to avoid hyperkalemia.
1 to 4 g intravenously as a 5% to 20% solution, rate not exceeding 150 mg/min; dosing frequency depends on indication (e.g., preeclampsia/eclampsia: 4-5 g IV loading then 1-2 g/hr infusion; hypomagnesemia: 1-2 g IV over 1-2 hours, may repeat based on serum magnesium levels).

Glucose: 2-3 hours (increased in renal impairment, diabetes); potassium: 12-24 hours (tissue redistribution); sodium/chloride: 20-30 minutes (rapid renal adjustment)
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal: >95% as free ions (K+, Na+, Cl-) and glucose metabolism products; biliary/fecal: <5%
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
